3d00da1de3 platform/x86: pcengines-apuv2: detect apuv4 board
GPIO stuff on APUv4 seems to be the same as on APUv2, so we just
need to match on DMI data.

d4ac8f83da platform/x86: pcengines-apuv2: fix simswap GPIO assignment
The mapping entry has to hold the GPIO line index instead of
controller's register number.

e8796c6c69 platform/x86: pmc_atom: Add Siemens CONNECT X300 to critclk_systems DMI table
The CONNECT X300 uses the PMC clock for on-board components and gets
stuck during boot if the clock is disabled. Therefore, add this
device to the critical systems list.
Tested on CONNECT X300.

133b2acee3 platform/x86: hp-wmi: Make buffer for HPWMI_FEATURE2_QUERY 128 bytes
At least on the HP Envy x360 15-cp0xxx model the WMI interface
for HPWMI_FEATURE2_QUERY requires an outsize of at least 128 bytes,
otherwise it fails with an error code 5 (HPWMI_RET_INVALID_PARAMETERS):

Dec 06 00:59:38 kernel: hp_wmi: query 0xd returned error 0x5

We do not care about the contents of the buffer, we just want to know
if the HPWMI_FEATURE2_QUERY command is supported.

This commits bumps the buffer size, fixing the error.

77dcc95e20 platform/mellanox: fix the mlx-bootctl sysfs
This is a follow-up commit for the sysfs attributes to change
from DRIVER_ATTR to DEVICE_ATTR according to some initial comments.
In such case, it's better to point the sysfs path to the device
itself instead of the driver. The ABI document is also updated.

937d6eefc7 Here's the main documentation changes for 5.5:
- Various kerneldoc script enhancements.
 
  - More RST conversions; those are slowing down as we run out of things to
    convert, but we're a ways from done still.
 
  - Dan's "maintainer profile entry" work landed at last.  Now we just need
    to get maintainers to fill in the profiles...
 
  - A reworking of the parallel build setup to work better with a variety of
    systems (and to not take over huge systems entirely in particular).
 
  - The MAINTAINERS file is now converted to RST during the build.
    Hopefully nobody ever tries to print this thing, or they will need to
    load a lot of paper.
 
  - A script and documentation making it easy for maintainers to add Link:
    tags at commit time.
 
 Also included is the removal of a bunch of spurious CR characters.

0da522107e compat_ioctl: remove most of fs/compat_ioctl.c
As part of the cleanup of some remaining y2038 issues, I came to
 fs/compat_ioctl.c, which still has a couple of commands that need support
 for time64_t.
 
 In completely unrelated work, I spent time on cleaning up parts of this
 file in the past, moving things out into drivers instead.
 
 After Al Viro reviewed an earlier version of this series and did a lot
 more of that cleanup, I decided to try to completely eliminate the rest
 of it and move it all into drivers.
 
 This series incorporates some of Al's work and many patches of my own,
 but in the end stops short of actually removing the last part, which is
 the scsi ioctl handlers. I have patches for those as well, but they need
 more testing or possibly a rewrite.

3f1b210a7f sound updates for 5.5-rc1
There have been some significant changes in the core side, both for
 ALSA and ASoC, while lots of development have been seen in SOF, as
 well as many small fixes/improvements for ASoC codecs and platforms.
 Below is a highlight in this cycle:
 
 Core:
 - The unification of PCM vmalloc buffer allocation helpers into the
   standard API
 - Clean up of the default PCM mmap handling for vmalloc & SG-buffer
 - Fix potential races at ALSA timer open
 - A few new PCM API extensions; just preliminary core changes, the
   actual changes in drivers will be merged in 5.6
 - Continued ASoC componentization works; now almost everything is a
   common ASoC component object.  A lot of refactoring and
   simplification have been done along with it.
 
 ASoC:
 - Many fixes to the Sound Open Firmware (SOF) code
 - Wake on voice support for Chromebooks
 - SPI support and trigger word detection for RT5677
 - New drivers for Analog Devices ADAU7118, Intel Cannonlake systems
   with RT1011 and RT5682, Texas Instruments TAS2562 and TAS2770
 
 HD-audio:
 - Improved Intel DSP configuration / probe code for SOF
 - Plumbing the legacy HD-audio driver with Intel SOF HDMI
 - DP-MST support for Nvidia HDMI codecs
 - Realtek quirks cleanups and new additions as usual
 
 Others:
 - Lots of refactoring and cleanups for FireWire; period-size sharing,
   h/w IRQ interval configuration, clock recovery improvements, etc
 - USB-audio: Scarlett mixer quirks
 - Cleanups of PCM calls in various drivers (including media and USB)
   to adapt the core API changes

f3e4f3fc8e platform/x86: hp-wmi: Fix ACPI errors caused by passing 0 as input size
The AML code implementing the WMI methods creates a variable length
field to hold the input data we pass like this:

        CreateDWordField (Arg1, 0x0C, DSZI)
        Local5 = DSZI /* \HWMC.DSZI */
        CreateField (Arg1, 0x80, (Local5 * 0x08), DAIN)

If we pass 0 as bios_args.datasize argument then (Local5 * 0x08)
is 0 which results in these errors:

[   71.973305] ACPI BIOS Error (bug): Attempt to CreateField of length zero (20190816/dsopcode-133)
[   71.973332] ACPI Error: Aborting method \HWMC due to previous error (AE_AML_OPERAND_VALUE) (20190816/psparse-529)
[   71.973413] ACPI Error: Aborting method \_SB.WMID.WMAA due to previous error (AE_AML_OPERAND_VALUE) (20190816/psparse-529)

And in our HPWMI_WIRELESS2_QUERY calls always failing. for read commands
like HPWMI_WIRELESS2_QUERY the DSZI value is not used / checked, except for
read commands where extra input is needed to specify exactly what to read.

So for HPWMI_WIRELESS2_QUERY we can safely pass the size of the expected
output as insize to hp_wmi_perform_query(), as we are already doing for all
other HPWMI_READ commands we send. Doing so fixes these errors.

16245db148 platform/x86: hp-wmi: Fix ACPI errors caused by too small buffer
The HP WMI calls may take up to 128 bytes of data as input, and
the AML methods implementing the WMI calls, declare a couple of fields for
accessing input in different sizes, specifycally the HWMC method contains:

        CreateField (Arg1, 0x80, 0x0400, D128)

Even though we do not use any of the WMI command-types which need a buffer
of this size, the APCI interpreter still tries to create it as it is
declared in generoc code at the top of the HWMC method which runs before
the code looks at which command-type is requested.

This results in many of these errors on many different HP laptop models:

[   14.459261] ACPI Error: Field [D128] at 1152 exceeds Buffer [NULL] size 160 (bits) (20170303/dsopcode-236)
[   14.459268] ACPI Error: Method parse/execution failed [\HWMC] (Node ffff8edcc61507f8), AE_AML_BUFFER_LIMIT (20170303/psparse-543)
[   14.459279] ACPI Error: Method parse/execution failed [\_SB.WMID.WMAA] (Node ffff8edcc61523c0), AE_AML_BUFFER_LIMIT (20170303/psparse-543)

This commit increases the size of the data element of the bios_args struct
to 128 bytes fixing these errors.

3300fdd630 platform/chrome: cros_ec: handle MKBP more events flag
The ChromeOS EC has support for signaling to the host that a single IRQ
can serve multiple MKBP (Matrix KeyBoard Protocol) events.

Doing this serves an optimization purpose, as it minimizes the number of
round-trips into the interrupt handling machinery, and it proves
beneficial to sensor timestamping as it keeps the desired synchronization
of event times between the two processors.

This patch adds kernel support for this EC feature, allowing the ec_irq
to loop until all events have been served.

was signalled to the AP by the EC as soon as possible after it happens.

First thing in the hard irq is the best place for this.

5306747118 iio / platform: cros_ec: Add cros-ec-sensorhub driver
Similar to HID sensor stack, the new driver sits between cros-ec-dev
and the IIO device drivers:

The EC based IIO device topology would be:

iio:device1 ->
   ...0/0000:00:1f.0/PNP0C09:00/GOOG0004:00/cros-ec-dev.6.auto/
                                            cros-ec-sensorhub.7.auto/
                                            cros-ec-accel.15.auto/
                                            iio:device1

It will be expanded to control EC sensor FIFO.

Add a new function to return the number of MEMS sensors available in a
ChromeOS Embedded Controller. It uses MOTIONSENSE_CMD_DUMP if available
or a specific memory map ACPI registers to find out.

Also, make check_features public as it can be useful for other drivers
to know what the Embedded Controller supports.

We need to convert all old gpio irqchips to pass the irqchip
setup along when adding the gpio_chip. For more info see
drivers/gpio/TODO.

For chained irqchips this is a pretty straight-forward
conversion. This driver requests the IRQ directly in the driver
so it needs to pass a NULL parent handler. We may revisit this
code later and pull reqular shared IRQ handler into
gpiolib, so leave a FIXME.

1832f2d8ff compat_ioctl: move more drivers to compat_ptr_ioctl
The .ioctl and .compat_ioctl file operations have the same prototype so
they can both point to the same function, which works great almost all
the time when all the commands are compatible.

One exception is the s390 architecture, where a compat pointer is only
31 bit wide, and converting it into a 64-bit pointer requires calling
compat_ptr(). Most drivers here will never run in s390, but since we now
have a generic helper for it, it's easy enough to use it consistently.

I double-checked all these drivers to ensure that all ioctl arguments
are used as pointers or are ignored, but are not interpreted as integer
values.
